Arcadis submits plan for haz-mat cleanup at airfield

Wednesday, April 21, 2004 - SHIRLEY -- Even as remediation of hazardous
materials continues at the former Army airfield off Route 2A in Ayer,
the contractor doing the cleanup has submitted a partially completed
design proposal for full-phase implementation of remediation.

Chuck Castelluccio, project manager for Arcadis, told the Devens
Restoration Advisory Board (RAB) at the Shirley Town Offices earlier
this month that a 60 percent design proposal has been submitted to the
BRAC Environmental Team at Devens. Project managers from state
Department of Environmental Protection (DEP) and the federal
Environmental Protection Agency (EPA) are on that team along with the
Base Realignment and Closure (BRAC) Office at Devens represents the
Army.

Two plumes of tetrachloroethylene (PCE), which was in cleaning fluid
used on parachutes, have migrated in groundwater at the former airfield.
The small plume migrating under Route 2A and the Merrimack Warehouse
property has become an isolated small pocket of contamination. But one
monitoring well in the area continues to steadily indicate PCE at a
level (11 parts per billion) slightly above EPA's required five parts
per billion.

Arcadis proposes a one-time injection of a fast-acting ingredient to
reduce PCE levels in the immediate level.

As for the source area on the airfield side of Route 2A, the remediation
proposal includes reactivating the soil vapor extraction system
installed in this area in the 1990s.
